Product Description

Alkaline Cotton Special Buffer Characterized Alkaline Dilution Developed for proper and highly efficient dyeing. Properties It provides linear pH increase when used with dosage. A problem of immediate pH increase doesn’t occur. It can increase pH to *1, 2 when necessary. Buffer character prevents pH from excessive increase. Even it is used more then *0 %, pH doesn’t reach *3. It generates a buffering system at the adjusted value of pH and decreases pH change to minimum. Its strong character of buffering, prevents bicarbonate caused pH drops. It is ideal for colors that havent reacted with the fabric and remain in the ***** the pH value required for dyeing fix. Colours are brighter and clearer. It is used for bleaching sensitive fibre. It economic thanks to facilities of stock, usage and labor cost. Usage Alkaline , by attenuated with 1/*5 water , is dosed average *0’ It can be used from **2 g/l for bleaching of special fabrics. It is used by abstracting with constant 3 g/l soda in the same liquor. Dye (%) With Cold Dye With Hot dye 0, 0 – 1, 5 0, *0 1, *0 1, 5 – 3, 0 1, *0 1, *5 3, 0 – 5, 0 1, *0 1, *5 5, 0 and above 1, *0 2, *0 Experimental Result of pH Change with Alkaline The amount necessary to add to a buffer solution to change pH one unit is called buffer value or buffer power. This value shows the buffering ability of a buffer system. When an acid or base is added to a buffer system ( or when a buffer solution made in a particular point added to a solution ) the value of the angle of pH change to the abscissa shows the tendency to buffer of that system. For instance, on a graph which has buffer amount on x axis and pH value on y axis, the smaller the angle between change of values and the x axis, the bigger the performance of the buffer system. pH change with use of Alkaline pH change with use of soda Warning : Information given in this brochure is prepared according to the
